Résumé

The work
described in this thesis focuses on the plasma deposition of amine polymer
films by cyclopropylamine onto metal oxide nanoparticles using a hollow cathode
magnetron reactor. Main objective of the thesis is to contribute to the
understanding of the plasma deposition mechanisms in order to produce highly
functionalized nanoparticles surfaces that can be exploited in a vast number of
applications, such as nanocomposites. In this frame and by employing both numerical
and experimental techniques, we investigate the impact of the process
conditions on the discharge dynamics and on the plasma deposition mechanisms.
Furthermore, we study the physicochemical properties of the plasma modified
nanomaterials, we describe in detail the influence of the amine plasma deposition
on the nanoparticles dispersibility and we show that high reactivity can be
achieved and can be exploited in order to obtain stable dispersions.
